Tire-shoe.

TIRE-SHOE.

Application filed October 27. 1915.

` To all 'whom it may o neem:

Be it known that I, DANIEL R. Teoras, a citizen of the United States, residing at Oklahoma, in the county of Oklahoma and State of Oklahoma, have invented certain new and useful Improvements 1n Tire- Shoes, of which the following is a specification.

An object of my invention is to provide a shoe which may be fitted in place and'secured upon a tire to provide a roughemng calk, and which may be used as a permanent attachment, or may be litted in place only in case of emergency to aid the wheel lm clearing a mud-hole or in climbing out of a rut.

A further object is to so construct the shoe that the same device made to a standard size may be adjusted for use on tires of various sizes, and to also provide aI fastoning;r means which will be capable of adjustment to compensate for the adjustment-s of the shoe structure proper.

Yet another object is to provide a fastening means which will permit the shoe to be fitted to and removed from the tire with the use of one hand so that the attachment may be fitted in the operative relation or removed while the operator is standing on the running board or step of the automobile or other vehicle to which lthe tire is fitted.

With these and other objects in view, my invention relates to certain novel features of construction and combinations of parts which will be hereinafter more fully described, pointed out in connect-ion with the accompanying drawings and set forth in the claims.

In the drawings:

Figure 1 is a vview taken transversely through a tire and rim with my lnventlon applied-thereon.

Fig. 2 Vis a view in elevation of the attachment.

Fig. 3 is a view in perspective of one of the membersI making.,r up the shoe. v

1n the adaptation of the invention as I illustrated in Fig. l., the shoe is shown fitted to a pneumatic tire, and this tire l is mounted., ,in pla'eeonthe rim or v'telly 2 of the wheel, these parts beine; ol standard form.

The members 5l and fl ol' the shoe are sublstantially duplicates, andA .are preferably made of. malleable iron .or some 'other metal capable of withstanding a considerable Shock and strain directly and suddenly im- Bpeoication of Letters Patent.

parted thereto. These members 8 and 4, when viewed in side elevation aresubstantially L-shaped with the inner angle curved gradually from the one arm to the other and the transverse flanges 5 and 6 are forme to extend substantially at right angles from the members 3 and' 4: and on opposite sides at the curved portion and on the inner edge of the longer arm.

The shorter arms of the members 3 and i have the openings 7 provided therethrough to be in registry, and these openings are so spaced apart that as the members 3 and l may he adjusted to obtain greater width of extension between the side arms thereof the openings will yet register and will permit the fitting of the bolts 8 and 9, or other suitable fastening means which may be employed. lVhen thel two members are adjusted and secured in place by the bolts 8 and 9, the laterally extending flanges 5 and 'G constitute a substantially U-shaped tire re spaced intervals along the depending ends of the long arms of the members 3 and 4,

which notches are preferably slight-ly in-\ clined downwardly from the outer edge, and also slightly flared at their opcnends. A hinge yoke 14 has the pin l5 secured across the open ends thereof, and 4by fitting this pin 15 inone of the openings 13, the yoke will depend with the looped portion thereofI disposed inwardly. A stirrup member 16 has a pin 17 disposed across the ends thereof to be received in the inclined notches 13 of the remaining'` shoe member and this `stirrup member 1G also has the loop disposed in-v wardly. A strap member 1S is hingedly connected with the yoke member 14 and is capable of free swinging movement thereon,

and at the opposite end of this straii member .18 the loops 19am provided to receive A volute shaped catch or buckle member 2l is-mounted on this pivot pinQO to be capable ot' swinging movement,

the strap 1.8 being'biincated :1t-the end 22 to accommodate the width ofthe member e to b e swung to 2l and to permit the sain the extended position.

In the use of the shoe, the bolts '8 and 9 are adjusted through the proper openings to bring the laterally lextending iianges and 6 to fit and bear against the tire, the yoke member 14 is -then adjusted to the proper position by the positioning of the 'pin V15 Wlthin one of the notches 13 of the 4me'mberA, the pin 17 of the stirrup member 16 is'adjusted to a corresponding notch on the member 3, and the strap member 18 .is swungup against the inner side of the rim or felly 2 after which the catch 21 is 4fitted.

through the loop of the strrup 16 and is swung to the position illustrated in Fig.' 1 Where it holds the strap `18 in bearing engagement with the felly and in' consequence secures the members 3 and 4 in'"a rigid mounting on the tire with the short `arms l 11, and 12 of these members in their overl26:

lapped relation forming an outstanding ca-lk` which is continued in the long arms of the members in proximity to the sides of the4 tlre.

Due to the fact that the yoke member 14:, the strap -member 18, and the stirrup member 16 will a all times present substantially the same' length and are not madev extensible,

" when'the members 3 and 4 are adjusted to accommodate tires of greater or lesser width',

.it .will bev necessary to adjust the pins A15 and.l

17 of the yoke and stirrup members to be received and heldin those notches 13 Where the proper bearing 'of the strap against the inner side of the vielly vvillrbe accomplished.

In the present disclosure, the pins and 1'( 4are illustrated as being fitted in theo'utermost notches lrhowever, this is only due tb the fact that the tire structure asillustrated is shown 'as being of more vthan usual height, and it will of course be understood that ordinari-ly Where the members 3 and are adjusted for a comparativelysmall size tirel '-such as shown in Fig. 1 of the drawing, the

. f position' to bee-received against the inner side pins 15and 17 would be adjusted to the in nermost notches 13. -V

It is preferable that a leather or other cushion strip 23 be 'securedby the riyets 24 on the inside of the curved portion of the ianges 5 andv 6 of one @of the members: to,JA

have its free ends project therefrom in a of the curvedv portion of the Iianges of the remaining member,- 'this cushion strip thus forming la protecting covering which is disposed between the tire and the shoe. 'It is shoe to be fitted in place after the Wheel has been stalled and under circumstances Where' it would be impossible toj t the usual rougheningV chains, however by making the arms 11 and 12 of slightl less transverse extent the structure could e adapted to be fitted in place and used during constant running of the vehicle and 'to take the place of the usual chains.

From theforegoing it Will be seen that the invention provides a shoe which may be readily lfitted in place from the running board lor step of the vehicle to which the tire is fitted. and which is provided with a securing means which may be readily actuated With one hand to either lock or unlock .the same.

While I have hereinshown and described only one specific form of shoe and fastening means, it will be understood that slight variations might be resorted to in the several parts Without departing from'the spirit and scope of my invention and hence I do not .wish to be limited to the e'xact,sh owing eX- cept for such limit bythe claims.

I claim:
